Hydraulic solenoid vharafu 12V 25/220992 reshiyo solenoid vharafu

Constant pressure overflow effect: Muhuwandu hwepombi throttling regulation system, pombi yehuwandu inopa chiyero chekuyerera. Kana iyo system pressure ichiwedzera, kuyerera kudiwa kunoderera. Panguva ino, vharuvhu yekuyamura inovhurwa, kuitira kuti kuyerera kwakawandisa kudzoke kumashure kwetangi, kuve nechokwadi kuti iyo yekuyamura valve inlet pressure, ndiko kuti, pombi yekubuda kwepombi inogara iripo (gomba revhavha rinowanzovhurwa nekudzvinyirira kushanduka) .

Kudzivirirwa kwekuchengetedza: Kana iyo system iri kushanda zvakajairika, valve yakavharwa. Chete kana mutoro unopfuura muganhu wakatarwa (system pressure inodarika iyo set pressure), iyo yakawandisa inovhurwa kuti iwedzere kudzivirira, kuitira kuti iyo system yekumanikidza haichawedzerwe (kazhinji iyo set pressure yevhavha yekuyamura iri 10% kusvika 20% yakakwirira kudarika yakanyanya kushanda kudzvinyirira kwehurongwa).

Taper vharafu mhando yakananga inoshanda yekuyamura vharafu. Mugumo wekuruboshwe wevhavhavhavhavha unopiwa ne bias disk kubata chitubu chekumanikidza, uye mugumo wekurudyi wetaper valve unopiwa piston inonyorovesa (kune rumwe rutivi, piston inonyorovesa inoita basa rekudzikisa kana taper valve. inovhurwa kana kuvharwa, iyo inoshandiswa kuvandudza kugadzikana kwevhavhavhavhavha yetaper; iyo piston kuburikidza neradial clearance yepiston, ichiita A left liquid pressure F = P · A (A ndiyo nzvimbo yepasi yepiston Kana iyo mvura inodzvinyirira F inobata pasi yakakura kudarika simba rechirimo, vharafu yekoni). chiteshi chinovhurika, uye mafuta anodeuka achidzokera kutangi kuburikidza nekoni valve port Pakangovhurwa chiteshi.
